I performed a migration using IMAP from FastMail a few days ago. It went well and migrated all my emails. I haven't changed the MX records immediately after the migration completed, but FastMail continued to receive emails.

Today I reconfigured MX records for laszlocsontos.com and pointed them to Zoho's mail servers. Now I'd like to update my inbox in Zoho with those few new emails I received in the meantime with FastMail.

• What procedure would you recommend for accomplishing that?
• If there are more ways to do that, please also elaborate on pros/cons and foreseeable side effects.

Many thanks for your advise!

Cheers,

László
